1.1 This specification covers metal cold-expansion fittings using metal compression-sleeves for use with cross-linked polyethylene (PEX) plastic pipe in ½-in., ¾-in., and 1-in. nominal diameters, whereby the PEX pipe is cold-expanded before fitting assembly. These cold-expansion fittings and metal compression-sleeves are intended for use in residential and commercial, hot and cold, potable water distribution systems, as well as sealed central heating, including under-floor heating systems, with continuous operation at pressures up to and including 100 psi (690 kPa), and at temperatures up to and including 180oF (82oC). 1.2 Included in this specification are the requirements for materials, workmanship, dimensions, burst pressure and sustained pressure, excessive temperature and pressure, and thermocycling tests, and markings to be used on the fittings and compression-sleeves. 1.3 The values stated in inch-pound units are to be regarded as the standard. The SI values stated in parentheses are provided for information purposes only. 1.4 The following precautionary caveat pertains only to the test method portion, Section 10, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
